Located on Samran Chai Khong Road by the Mekong River, directly across from the Tha Kham municipal pier and the Mukdahan immigration checkpoint, the temple houses the revered "Phra Chao Ong Luang," a brick and mortar Buddha statue. This statue has a lap width of 2.20 meters, while its total height, including the crown, reaches 2 meters. It is considered a significant symbol of the city, having been constructed even before the establishment of Mukdahan, although the exact period of its creation remains undocumented. Legend has it that in the year B.E. 2310, when Lady Kinri was overseeing workers clearing the jungle near the Seven Tops palm tree during the city's founding, two Buddha statues were discovered: a large brick and mortar statue and a smaller iron statue nestled beneath a Bodhi tree. In honor of this discovery, Lady Kinri established a temple in the area to enshrine both statues. One day, as the resident monk entered the temple to make offerings, he noticed that the iron statue was missing. Upon searching the surrounding area, he found the iron statue had returned to its original resting place beneath the Bodhi tree, where it had sunk into the earth, leaving only the crown visible—an astonishing sight. Consequently, Lady Kinri built a shrine at that location and named the smaller statue "Phra Lub Lek" (the Iron Buddha), while the larger statue was placed within the temple and has since been known as "Phra Chao Ong Luang." This great Buddha statue has stood as a beloved icon of Mukdahan ever since.
